Abstract: In the title centrosymmetric mononuclear nickel(II) compound, [Ni(C₁₉H₁₅N₅)₂(H₂O)₂](ClO₄)₂·4H₂O, the central Ni^II atom is coordinated by four N atoms from two 4-(4-methylphenyl)-3,5-bis(2-pyridyl)-4H-1,2,4-triazole ligands, and two O atoms from two water molecules. The coordination geometry is slightly distorted octahedral. In the crystal structure, the molecules are linked together by intermolecular O-HO hydrogen bonds.
